Can someone explain/show me how to do this?Absolute Value Functions
otez555 [7]
Domain: The values that X could take, so domain = (-∞,+∞)

Range: The values that the dependant variable, f(x), could take. Since we can't get negative numbers, it'd be range = [0,+∞)

X and Y intercepts: The points in which you touch the axis. On this case the only one is the point (0,0).

Increasing and decreasing refers to the region where the function increases or decreases. It increases on (0,∞), and decreases on (-∞,0).

Sorry, but I don't understand what you mean with "transformations", at least the way you're written it. If you give me a bit more of info, I'll do my best to help :)

3. Find m D<br> (2x+14)<br> (x + 7)<br> E<br> B<br> 60<br> 23<br> 53<br> 30
pickupchik [31]

Answer:

Step-by-step explanation:

∠ABC + ∠CBD = 90 so filling in the expressions for these angles:

(2x + 14) + (x + 7) = 90 and

3x + 21 = 90 and

3x = 69 so

x = 23. To find the measure of angle ABC in particular, we sub in a 23 for x:

x + 7 --> 23 + 7 = 30°, the last choice there.

Solve the following absolute value equation.
dolphi86 [110]

Hey there!

|\displaystyle\frac{x-1}{2} |=7

Let's say that x-1 is negative:

\displaystyle\frac{-x+1}{2} =7

The first step is to multiply both sides by 2:

\text{-x+1=14}

Now, move 1 to the right, using the opposite operation:

\text{-x=14-1}

\text{-x=13}

Divide both sides by -1:

\text{x=-13}

  • Note: Since the negative sign is already entered, all you need to enter is 13.

I hope you find my answer helpful.

Good luck!

Have a great day!
